Five of them have a large, black, semicircular area on the elytral base and plumose setae in the prosternal channel. Peridinetus illabes is the only species without a patch of white setae on the elytral flank ( Fig. 36 ). Females have the dorsal rostral groove near the basal third ( Fig. 44 ); males have the antenna inserted near the distal fourth ( Fig. 36 ; more basally in all other species). Description. Total length 3.8–4.8 mm , standard length 3.7–4.7 mm , width 2.1–2.5 mm . Integument black, head, rostrum, tibia and tarsi reddish to dark brown, antenna red; color pattern formed by red, olive green, white and small dark setae, basal half of elytra with conspicuous semicircular black area, anterior half of pronotum red ( Fig. 35 ), elytral flank with semicircular dark area without adjacent white spot ( Fig. 36 ), interstria 5 without white spot in front of ridge. Frons shallowly depressed (male) or convex (female). Rostrum 0.79–0.89 × length of pronotum, antenna inserted in apical third of rostrum (male) or before middle (female); female with dorsal groove at about mid length between antennal insertion and base of rostrum ( Fig. 44 ). Pronotum 0.92–1.00 × longer than wide, sides subparallel in basal half and then curved inward without lateral tumidity or raised setae, front tubulate; disk microreticulate, impunctate. Prosternum with plumose setae. Elytra 1.33–1.39 × longer than wide, humeri 1.44–1.58 × wider than pronotum, subtriangular, sides gradually converging in basal two thirds; striae distinct, interstriae 3 and 5 ridged in distal third, 7 and 9 throughout, preapical callus moderate; tarsal claws subconnate.
